| 摘要: |
| 在山西运城盐池湖区采到的藻类植物共5门(不包括硅藻门),30科,70属,222种(含变种和变型).其中蓝藻门4 科17属35种,绿藻门19科40属93种,裸藻门5科10属83种,黄藻门1科1属2种,轮藻门1科2属9种.该湖区的水体根据含盐量的不同可分为4种类型:淡水水体(含盐量<0.05%)、混盐水体(含盐量0.05%-3%)、真盐水体(含盐量 3%-4%)和高盐水体(含盐量>4%).由于受含盐量的影响,藻类植物在4种水体中的分布有明显差异,随含盐量增加,种类数减少. |

| Abstract: |
| A total of 222 species of algae were collected Irom the salt lake area in Yuncheng, Shan xi Province, North China, representing 5 didivisions, 30families and 70 genera. Among them 35 speces from 4 families and 17genera in Cyanophyta, 93 speces from 19 families and 40 genera in Chlorophyta, 83 speces from 5 families and 10 genera in Euglenophyta, 2 speces from 1 family and 1 genera in Xanthophyta, 9 speces from 1 family and 2 genera in Charophyta. Concerning the salt concentration of the water, 4 types can be divide, i. e. fresh water(salt concentration < 0. O5 %), mesohalinous water(salt concentration 0. O5%-3%), euhalinous water(salt concentration 3%-4%)and polyhalinous water(salt concentration > 4%).Because of the effect of different salt concentration the difference is evident in the distribution of alage in 4 types of the water.It is shown that the higher salinity, the fewer number of species. |
